Found the problem. R7783 should be 0 ohm but was about 10k ohm. Replaced with a new one and backlight is working again.
Does someone know how it is possible that the ressistor go bad?

Thanks, I already did that. I checked R7723 & R774 and they measure both 10ohm. All pins on J4915 are connected.Leave a comment:

Hi all, my keyboard lighting stopped working. I opened the casing to clean the fans, and after that the keyboard lighting stopped working. I did not unscrew something. I see the bars going up and down when pressing on the keyboard lighting keys. Already did SMC, PRAM reset.
Did I maybe short something on the motherboard? -
